摘要

在变化的磁场中，导体中产生的涡流产生与导电材料中产生的热量成正比的阻尼力。在直流直线电机系统中，在线圈下增加导电板以阻尼力，提高电机的动态响应。在前期工作中，利用图像法得到了磁场分布公式，从而计算了导体中感应的涡流。然后计算等效电阻和电导处的电感，得到阻尼力。利用阻尼力公式对短行程直流电动机涡流阻尼的设计进行了优化，得到了产生最大阻尼力时的电机转速。

Analysis of eddy current damping for short-stroke DC linear motor

Eddy currents induced in a conductor in a changing magnetic field produce a damping force proportional to the heat generated in the conductive material. In the DC linear motor system, the conductive plate is added under coils for damping force to improve motor's dynamic response. In the preliminary work, the formula of magnetic field distribution is obtained by the method of images, so the eddy current inducted in the conductor is calculated. Then the damping force is obtained after the equivalent resistance and inductance of conductance place are calculated. The design of eddy current damping for short-stroke DC linear motor is optimized by the formula of damping force, and obtains the speed of mover when maximal damping force is induced.
